You're asking this to get good games ? well, if so, Then I'd recommend Quake 2 and Duke Nukem 3D (PC) those require pretty low system requirements such as video and so, but they also have a hi-graphics option for powerful machines

If you want my opinion... Destiny is amongst the best games I've played, although it lacks story and the development reels showed more promise than the final game. It also proves that the Xbox One and PS4 were too early for their time. Halo, for me, died off a while ago. But it can be amongst the list of great games. The Portal series is old, but it can join the group. TES: Skyrim can be added to the list, I refused to play it on a console and it feels smoother on a keyboard and mouse. GTAV also looked pretty awesome, even on the next generation systems.
